The 23-year-old `Someone Like You` hitmaker has risen to the top of the Sunday Times Rich List thanks to the huge success of her album `21`, which sold in excess of 20million copies worldwide.
Steve Redmond, of the Entertainment Retailers Association, told The Sun newspaper: "Adele`s been the success story of the past year by a mile. You only get an Adele once every ten years. It`s success on a ginormous scale."
Cheryl Cole, Leona Lewis and Katie Melua are all in second place with an impressive £12million, while Adele`s fellow Brit School alum Jessie J has made her debut appearance on the list for those aged 30 and under, with a fortune of £5million.
The rundown of Britain`s highest-earning young actors is once again topped by `Harry Potter` star Daniel Radcliffe, 22, and his £54million, up £6million from last year thanks to his latest film, `The Woman In Black`. In second place is `Twilight` star Robert Pattinson, 25, who has increased his wealth by £8million since last year, taking his total to £40million, while Keira Knightley, 27, still has an estimated £30million, the same as last year.
